Bicycle set-up dimensions and cycling kinematic data are important components of bicycle fitting and cyclist testing protocols. However, there are no guidelines on how bicycles should be measured and how kinematic data should be collected to increase the reliability of outcomes. This article proposes a consensus regarding bicycle set-up dimensions and recommendations for collecting cycling-related kinematic data. Four core members recruited panellists, prepared the document to review in each round for panellists, analysed the scores and comments of the expert panellists, reported the decisions and communicated with panellists. Fourteen experts with experience in research involving cycling kinematics and/or bicycle fitting agreed to participate as panellists. An initial list of 17 statements was proposed, rated using a five-point Likert scale and commented on by panellists in three rounds of anonymous surveys following a Delphi procedure. The consensus was agreed upon when more than 80% of the panellists scored the statement with values of 4 and 5 (moderately and strongly agree) with an interquartile range of less than or equal to 1. A consensus was achieved for eight statements addressing bicycle set-up dimensions (e.g. saddle height, saddle setback, etc.) and nine statements for cycling kinematic assessment (e.g. kinematic method, two-dimensional methodology, etc.). This consensus statement provides a list of recommendations about how bicycle set-up dimensions should be measured and the best practices for collecting cycling kinematic data. These recommendations should improve the transparency, reproducibility, standardisation and interpretation of bicycle measurements and cycling kinematic data for researchers, bicycle fitters and cycling related practitioners.

自行车设置尺寸和骑行运动学数据是自行车装配和骑行者测试协议的重要组成部分。然而，目前还没有关于如何测量自行车以及如何收集运动学数据以提高结果可靠性的指南。本文提出了关于自行车设置尺寸的共识以及收集自行车相关运动学数据的建议。四位核心成员招募小组成员，准备小组成员每轮评审的文件，分析专家小组成员的评分和意见，报告决定并与小组成员进行沟通。十四位具有自行车运动学和/或自行车配件研究经验的专家同意作为小组成员参加。初步提出了 17 条陈述的清单，使用五点李克特量表进行评级，并由小组成员按照德尔菲程序在三轮匿名调查中发表评论。当超过 80% 的小组成员给该陈述打分为 4 和 5（中等同意和强烈同意）且四分位距小于或等于 1 时，就达成了共识。针对自行车组的八项陈述达成了共识向上尺寸（例如鞍座高度、鞍座后退等）和自行车运动学评估的九个陈述（例如运动学方法、二维方法学等）。该共识声明提供了一系列关于如何测量自行车设置尺寸以及收集自行车运动学数据的最佳实践的建议。这些建议应提高研究人员、自行车装配工和自行车相关从业者自行车测量和自行车运动学数据的透明度、可重复性、标准化和解释。
